Subject: suspend script fails with 2.6.31, related to stdout?

a pm-suspend hook fails with 2.6.31 (which does not under 2.6.30). the 
error as follows:
---

/etc/pm/sleep.d/11netcfg resume suspend: /bin/stty: standard input: 
Inappropriate ioctl for device

ive been tracking down the script, and it all comes down to iwlist 
(which is used to scan for networks) which prints outputs to stdout. i 
dont know how to debug this any further.. does anyone have any idea?
